Possible Causes

User did not perform the reset procedure, Control board timer glitch, Flow meter not detecting proper rinse volume, Stuck limescale sensor (if equipped)

How to Fix / Troubleshooting

Safety first: Unplug before extended cleaning.

Steps:

  • Follow manual reset steps: Many Capresso models require holding a specific button (e.g., CLEAN or BREW) for several seconds after descaling to reset the indicator. Refer to your user manual.
  • Complete full cycle: Ensure you ran the entire descaling and rinse cycle as described, including the required number of rinse tanks.
  • Power cycle: Unplug the machine for 5–10 minutes, then plug back in and attempt the reset again.
  • Descale again if needed: If the machine still indicates scale, run another descaling cycle; heavy buildup may require multiple treatments.
  • Control issue: If the indicator never clears, the control board’s timer or sensor input may be faulty and may require board replacement.
